For those who believe in UFOs, this is how it typically goes: you see a strange looking cloud in the sky, you definitely take a photo. For the more serious observers, they fix some high tech cameras and patiently wait for something strange to happen. And then they film their strange sightings. These things happened in Florida in the U.S. and in Sydney, Australia, recently.

UFO or Spaceship Cloud in Florida?

Here is an example of a person who took a photo of his strange sighting, hoping to find some answers later.

"We were taking a walk through the hills with some friends when this giant disk cloud appeared from over the hill. It looks like a UFO and I have never seen anything like this before. It moved slowly and made no sound, if its a UFO, its trying to look like a cloud. The bottom was fluffily like a jellyfish, the top smooth like a ceramic bowl. It was about 400-500 meters across. Has anyone else reported this?"
